The Winfrith Nuclear research station was opened in 1957, to expand the UK’s civil nuclear research programme and therefore test a variety of new nuclear reactor designs. In total Winfrith had nine nuclear reactors which were used for research anddeveloping the best form of nuclear power. The site closed its last reactor in 1995 and has since been decommissioning.
As this site was a nuclear area, all the ground water and surface water is regarded as contaminated. It therefore cannot be discharged off-site and must be stored and tankered away.
Existing chambers were used to collect the ground and surface water run-off and SPEL provided pumping equipment to be fitted inside these chambers instead of providing new GRP chambers, due to every shovel of earth having to be tested and disposed of correctly, therefore using existing chambers was hugely benificial. These chambers collected all of the water and then pumped the water into the connected SPEL Tankstor aboveground tanks so that the water could be stored until a contractor collected it and removed it from the site. The outlets of these tanks were therefore fitted with a 4″ PN10 flanged knife gate valve that was connected to a Bauer coupling so that the waste removal contractor could easily connect up and remove the potentially contaminated water.
SPEL provided a variety of SPEL Tankstor above ground tanks in both vertical and horizontal formats and capacities ranging from 5,000 litres up to 65,000 litres. SPEL also manufactured a solitary Vertical Packaged Pumping Station at 1.8m internal diameter (SPEL 300 Series) and 3.5 metres deep to an area where there was no preinstalled chamber that could be used for pumping into the nearby SPEL Tankstor above ground tank.
